Picomotor Actuator, Ultra-High Vacuum, 0.5 in. Travel, 0.375 in. Shank

Our Picomotor actuators have a step size of less than 30 nm per step, allowing for very small, controlled movements. Note that the step size for open-loop picomotors varies from step to step and between forward and backward directions, and is directly related to payload – hence, position feedback should be provided by an external signal when operating an open-loop picomotor. For vacuum applications requiring absolute position calibration and high repeatability, consider a Vacuum Compatible Closed-Loop Picomotor actuator.

All of our vacuum compatible and ultra-high vacuum compatible Picomotor actuators come with short, Teflon-coated leads so you can make connections to your vacuum-chamber feedthrough. If, however, you are working with X-rays or other high-radiation applications, we offer versions with Kapton-coated wire extensions.

We offer both Open-Loop Picomotor controllers and drivers as well as Closed-Loop Picomotor controllers and drivers. You have two interface options with the controller system: hand pad or computer, both providing plug-and-play use. Alternatively for open-loop actuators, you may choose to use our TTL/Analog Picomotor driver.

The Picomotor actuator moves when voltage is applied to the piezo, changing its length and in turn moving the jaws which turn the screw. When no power is applied, the actuator does not move. You can feel confident that your set-up will stay put, even when you power down your system.

With a load capacity of 5 lbs (22 N) for our standard sized Picomotor actuators and 3 lbs (13 N) for our tiny Picomotor actuator, they feature a substantial push force.
